Bladder tissue was successfully grown from baboon bone marrow. It was kept functional for two years. This success is promising for success with human tissue over the next few years. Scientists from Stanley Manne Children’s Research Institute at Ann & Robert H. Lurie Children’s Hospital of Chicago and Northwestern University have succeeded in regenerating fully …
Neuralink has officially implanted its first brain chip into an actual human. The person is recovering well and the device is detecting neuron spiking. Those who suffer from ALS or spinal cord injury are the people who should apply for device. The Neuralink mission is to create a generalized brain interface to restore autonomy to …
Researchers published in the peer-reviewed Nature in Dec 2022 estimated that there were 14.83 million excess deaths globally (2020-2022), 2.74 times more deaths than the 5.42 million reported as due to COVID-19 for the period. The Global Covid deaths greatly in declined in 2023 but the excess deaths continued at far higher levels. In Japan …
The worldwide prevalence of childhood obesity has risen dramatically over the last 30 years. In the United States, approximately 20% of school-age children are considered obese, resulting in a significant public health concern. The etiology of childhood obesity is complex, and both genetic and environmental factors contribute to the development of the disease. Recently, early-life …
Brian Wang and Randy Kirk discussed the expected biggest science and technology stories of 2024. The potentially biggest development in 2024 could be antiaging science reaching a milestone of doubling the remaining lifespan of a mouse. The Longevity Escape velocity program has take four promising anti-aging treatments and applied them in various combinations to a …
1. AGI could be achieved or we will get even closer. There will OpenAI releasing GPT5 and updates of Google LLM like improved Gemini. Definition’s for AI AGI = artificial general intelligence = a machine that performs at the level of an average (median) human. ASI = artificial superintelligence = a machine that performs at …
New high-performance ultrafast lasers are being made on nanophotonic chips. The new work centers on miniaturizing mode-lock lasers — a unique laser that emits a train of ultrashort, coherent light pulses in femtosecond intervals, which is an astonishing quadrillionth of a second. Ultrafast mode-locked lasers are indispensable to unlocking the secrets of the fastest timescales …
Researchers have now taken a step toward that vision of molecular systems that repair cells inside the human body. Molecular repair built from a patient’s own cells will eventually ferret out cancer, repair injured tissue, and even remove plaque from blood vessels. They have gotten tracheal cells to form coordinated groups called organoids that can …
UCLA chemists have made dramatic improvements in organic chemistry. They use oxygen, copper ‘scissors’ to make cheaper drug treatments possible. Zhiqi He et al, Aminodealkenylation: Ozonolysis and copper catalysis convert C(sp 3 )–C(sp 2 ) bonds to C(sp 3 )–N bonds, Science (2023). Editor’s summary Reactions that form carbon–nitrogen bonds most often target carbon centers …
Approaches to achieving radical life extension involve many scientific unknowns. There is uncertainty around whether the different forms of aging damage can be repaired. There is an approach to immortality that replaces scientific unknowns with huge technical challenges. The technically challenging approach is: 1. Rejuvenate the body by growing a body using an egg cell …
The Ship of Theseus is a thought experiment about whether an object which has had all of its original components replaced remains the same object. Theseus, the mythical Greek founder-king of Athens, rescued the children of Athens from King Minos after slaying the minotaur and then escaped onto a ship going to Delos. Each year, …
